Morphology

hyperventilate = ventilate (semi-transparent) = hyper + ventilate

The prefix hyper- clearly indicates excess, but the specialized medical sense of ventilate makes the full meaning only partly predictable.

Etymology

Hyperventilate comes from hyper- meaning 'over' or 'too much' and ventilate meaning 'move air'. So, to hyperventilate is to breathe too much or too quickly, which often happens in a panic and can make you feel dizzy.
